Out of the Sun

Read Out of the Sun Storyline:

Harry Barnett is shocked to learn that he has a son - David Venning, a
brilliant mathematician, now languishing in hospital in a diabetic coma.
And this is only the first and smallest of the mysteries he is about to
encounter.It is not known whether David's condition is due to
an accident or a suicide attempt. But Harry discovers that his
mathematical notebooks are missing from the hotel room where he was
found. And two other scientists employed by the same American
forecasting institute have died in suspicious circumstances. Driven
on by the slim hope of saving the son he never knew he had, Harry goes
in search of the truth and finds himself entangled in several different
kinds of conspiracy - none of which he ought to stand the slightest
chance of defeating.
